October 25, 2011 – 5,293 Global Earthquakes by East and West Longitude: I downloaded 5,293 global earthquakes; from January 1, 1973 to October 24, 2011; with a magnitude of 6.0 or greater. I then divided them into east and west longitude. The results are displayed in the chart above.
East longitude had a total of 3,427 quakes, while west saw 1,866. The average was 2,646.5. That means east had 780.5 more quakes than the average and West had -780.5. East had 1,561 more tremors than west.
This is similar to a study I did of 346 global earthquakes, of magnitude 7.0 or higher, over the same time period. East longitude had significantly more quakes than west. This is because east longitude includes the very earthquake prone countries of Japan, Indonesia, Russia, the Solomon Islands, Papua New Guinea and the Philippines. These six countries accounted for 61% of the total east longitude quakes. Additionally, two of the most powerful earthquakes, over the last 39 years, occurred in Japan (March 11, 2011) and Indonesia (December 26, 2004). The Indonesia mega-quake was responsible for 227, 878 deaths; primarily from the subsequent tsunami. Whole islands were washed clean of any living soul. This was the worst disaster in recent memory, in terms of death toll.
The Japanese super-quake of March 11, 2011 was the worst disaster in modern remembrance, in terms of dollar total. Extensive damage was generated relative to buildings, crops, farmlands, a nuclear generating station and infrastructure. Where will the next mammoth quake strike?
